Effective Learning - Pro-Active, Active or Re-Active

Learning is day to day process. We can’t stop. We cannot avoid. Hence, we are on continuous learning path. I tried to look various ways in which we learn and which one is commonly used and most effective.
In first form of learning, we get a book or search on net for new topic. I will call this as Active learning. We often end up with reading few opening pages/topics. Can you recall how many books you have read from start to end?
It's time now to use and apply the knowledge. This is start of re-active learning stage. We see a barrier or knowledge gap and then try to learn about topic and go ahead.
It is communicated and repeated on all platforms that we should be pro-active. ( This phrase more common during appraisal period in IT Industry ). This is third form of Active.
There is a thin line between Active and Pro-active learning. In case of active you do not have visible time frame for its application. i.e School or college days. In Pro-active learning you know when you are likely to need/use that knowledge.

Now, if we compare to make out which form of learning is common? and which one is effective ? 1. Active 2. Re-Active 2.Pro-active. Irrespective of how much emphasis you give to Active or Pro-active learning, common learning is Re-active. It increases stress wherein you need to learn as well as apply. All said and done, it most effective learning forms.
Now, some unanswered questions? Does re-active learning means we are not disciplined? or work-life does not allow you to be disciplined or organized ? or we work in the area which is always new or different than past experience ? What do you think?
